Once again greetings to everyone!

Please help me if you know what problem my plants might have.

Strain - Auto Power Plant
Lighting - Pureled 480w 25% distance from the plant 65cm
Soil - BioBizz light mix
Fertilizers - Advance nutritions

The plants are watered every 3-4 days and fertilized every other watering, the amount of water for watering is about 3.5 liters per 20L AirPot

So let me tell you my problem.

3 weeks ago, flowering started for two plants and then the problems started. The leaves of the plant curl inward and the edge of the leaf becomes pointed. I first thought that the problem was the height of the lamp, so I raised it, then I thought that the problem was wind burn, so I reduced the fans. And the last thing I did was a flush on 24.9 because I suspected nitrogen poisoning, but that didn't seem to help either. I did the flush with 30L of water PH 6.8 and after the flush I did not add fertilizer.

The temperature in the box is not perfect, it ranges between 19 and 22 degrees and I am not able to heat the box.

My thought when I saw the pics was over watering. You pots are about 5 gallon so they will dry out slowly especially after doing a flush(and depending on your root ball/plant uptake). I would water with a bit less that that. In the past I have used 2 gallons spread out over four 3 gallon pots(so a half gallon or 2 liters per 12 liter pot). Cannabis likes a wet/dry cycle. I go by weight of the pot and feeling how moist the soil is about 1 knuckle deep to determine when to water. Nice looking flowers, Betrion.
 
And I can’t tell if you have pans under the plants. If you do and the run off is allowed to stay in the pans, that can be a problem for the roots at the bottom of the pot. They will be constantly soaked.
 
I'm afraid that I won't be able to save the plants, I'll try to reduce the amount of nitrogen at the next watering... This has been going on for 3 weeks now and I can't bring them back to normal, I'm afraid they'll die...

Pots are 19L.

I’m having the same problem with my autos. I quit feeding veg nutes two weeks ago and only have been watering with cal mag but my leaves on a couple plants continue to look I’ll from what appears to be to much nitrogen still. I did use preloaded soil but would think that those nutes would be running out by now. I planned to start bloom nutes this week but am almost afraid that it would make things worse. My PH checks out both in and out and I have been watering about every three days when my pots get light. Looking forward to folks chiming in here

They don’t look anywhere near death to me. I would back off your watering. Looks like you are using Advanced Nutrients. I am trying them out now and have found going by their feeding chart that there is too much nitrogen during flower. I am trying to use about half the amount of ‘Grow’ liquid per feeding to see if that helps. I can’t say yet if that will help.
 
My plants do that when they are thirsty.
He could feel underneath the pots to see if there is water pooling underneath. Could be they need more water too. The ‘knuckle test’ would help to clear that up though. If they are thirsty, they should recover shortly after watering especially after flushing the pots. I would think too little water would make them cycle between looking healthy then thirsty instead of droopy all the time.
 
Surprise!!!

I came home from work, I open the box when I have something to see! One plant has fully recovered and put up leaves! Looks like the flush worked!

@Hippie420 hello mate! Trust me, for 2 weeks i could not get this plant to look normal... Leafs down all the time... U can still see it on the upper right plant on the last pitcure.

I'm waiting for Cartman to chime in. He's our resident auto expert. It could be a problem, or it could be just a quirk of the strain. Sounds like it's getting back to what you like, so time will tell. Best of luck. It looks like it's budding up nicely.
